A nickel-catalyzed aryl-difluoroalkylation of alkynes is developed. A series of trisubstituted fluoroalkenes can be obtained in a highly stereoselective manner by mixing of simple starting materials alkynes, ethyl bromodifluoroacetate, and arylboronic acids in the presence of nickel catalyst. This method features low-cost catalyst, mild reaction conditions, and excellent functional group compatibility.

Key words: nickel catalysis, alkynes, stereoselective, aryl-difluoroalkylation, fluorine chemistry
